[Bug 722285] Re: timeline only shows 320 times the zoom slider setting

 

I am now working on a long project (2 hours), made itself of long video-
clips ("rushes" of around 30 min each), which I chop into shorter clips
on the tracks. I am using 1.4.2 with Joseph Eoff's patch.

Here are few abnormal behaviors:
1. When right- clicking on a clip on a track and choosing "properties", the play-head goes to position 0 (as soon as the properties window pops up, before doing anything)
2. Same behavior when "saving as"
3. Most actions take very long to complete (around 1 minute for most of them), with the screen turning gray. 

Since I used neither the "classical" version (provided by Ubuntu or
Canonical repositories) nor the non-patched 1.4.2 version on long
projects and long imported video-clips, I don't know if this is due to
1.4.2, to Joseph's patch, or to the fact that both the project and the
material it deals with are unusually long.

Title:
  timeline only shows 320 times the zoom slider setting

Status in libcairo  -  cairo vector graphics library:
  Confirmed
Status in OpenShot Video Editor:
  Confirmed

Bug description:
  The timeline only shows the first (320*zoom seeting) seconds of a project.
  So if the zoom slider setting is set to 1 s, the timeline stops at 5'20'' (=320'')
  if it set to 2 s, it stops at 10'40'' (=640''), 4 s it stops at 21'20'' (=1280''), etc.

  How to reproduce:
  -launch OpenShot and create a new project of 60 min
  -with the default 8 s zoom setting you can only move the timeline up to 42'40'' (=2560 = 320*8)
  -try zooming in and see the timeline shorten as you zoom more

  1. Ubuntu 10.10 x64
  2. PPA installation
  3. OpenShot 1.3.0
